Although there are no traditional IBM manuals for zPDT Users, there are several other
sources, including some excellent IBM Redbooks for Technical Information.
Here we provide some pointers and links to what is currenly available.

General Information:

One caution regarding the following references: some details concerning how the zPDT (IBM z1090) can be
obtained have already changed. IBM will not sell or otherwise distribute the zPDT code or z1090 USB
hardware key. ITC will be the only source for these products in the USA.
